SAMUEL G. MERRIGK, OF PHILADELPHIA, PENNSYLVANIA.

GAS -PURIFIER.

To all whom it may concern:

Be it known that I, SAMUEL Gr. Mnaniok, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, hage invented a new and useful (Jras-Iuritienof which the following is a specification. v

This invention relates to a new and useful improvement in condensers and more particularly to the type for use in connection with smoke, gases and vapors.

It has for an object to provide an improvement over my former patent No. (589,682, granted December 24th, 1901, whereby an apparatus is produced simple in construction, efiicient in service comprising a minimum of parts and producing a new and useful result. The parts thereof are arranged to form a complete unitary structure reducing the power applied and by a compressing action completely separating and breaking up the gaseous products. I

Figure 1 represents a condenser embody ing my invention and is a section taken on line aca1 Fig. 2. Fig. 2 represents a section of the same on line y-y Fig. 1. Fig. 8 represents a detail of construction.

'For the purpose of illustrating my invention I have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

1 designates a suitable casing mounted in any desired manner and having an inlet opening 2 therein adapted to receive, in the present instance asupply pipe3 by means of which the smoke, vapor and like gases are introduced into the interior of the said casing, while 4 designates an outlet opening adapted, as here shown, to receive an exhaust pipe 5-by way of which any remainingsmoke or vapor escapes to the eXteriorof the receptacle. J

6 designates a plate or partition suitably secured to the casing 1 and separating the receiver 1 into receiving and delivery chambers 7 and 7 8 designates a shaft suitably mounted for rotation in the casing 1 and passing trans- Specification of Letters Patent.

versely there-through, the same having a suitable pulley 9 fixedly mounted-thereon and adapted to receive power from any suitable source. This shaft 8 carries thereon a tubular member 10 having a spiral partition I 11 running throughout the length thereof as seen in Fig; 1 of the partition 6 inthe receiving chamber is preferably formed of substantially the shape of a frustum of a cone, while the portion on the other side of said partition has approximately a cylindrical form which is preferably and for the highest efficiency constructed of a length substantially greater than the length of the frustinn portion, measurements being taken from the point aa, as indicated in Fig. 1.

Special attention is directed to the elongated, cylindrical form of the tubular member forming a continuation of the frustum portion thereof since the function of this part is an important one in that it produces a choking or compressing effect to the gases and liquids passing through the spirals which makes the separating action an exceedingly efiicient one in that. the compression and purifying instead of ceasing at the end of the frustum portion is continued through the cylindrical portion thus l1lcreasing the efiiciency of the apparatus to a material degree.

In order to prevent the gas from passing between the partition 6 and the outside of the tubular member 10 flanges 12 are secured to the outer circumference of the member 10 |and in close proximity to the partition 6 whereby upon rotation of the member 10 the liquid is carried around between the flanges 12 forming an effective seal to prevent leakage of the gas. In practice it is preferable to employ suit-able packing devices adjacent the flanges 12 in order to aid in forming a perfect seal.

- At the outlet end of the tubular member 10 a batlle plate 13 is preferably located which serves the purpose of breaking up the liquid within the tank and effecting a thorough mixture of the same with the entering gas while adjacent to the inlet end of the tubu ar member is a somewhat similar plate lat which, as shown in Fig. 2, passes in close proximity to the said inlet: and extends for some little distance on either side of the tubular member. Q

designates av plate preferably perforated and suitably supported upon brackets in secured tothe bottom of the casing 1, the object of said plate being to prevent too violent agitation'of the liquid in the lower levels of the receptacle so that the heavier contained liquids may be easily disengaged or separated and collected. in the bottom of the tank from which they may be removed by means of a blow-off valve 17 or the like as may be desired.

Special attention is directed to the frustum formation wherein the smoke and gases are picked up and conveyed through the tubular member and it will also be noted that the substantially horimnt'al and cylindrical continuation of the frustum permits a full compression and purifying ot the gas taken in that is, where the horizontal section meets the conical section is the point of maximum compression and minimum condensation. The gas, confined within the horizontal section and subjected to the action of the water, is more thoroughly washed and purified by reason of the compression and condensation before mentioned.

It will of course be understood that the shaft 8 located a approximately the liquid level of the casing so that when the shaft 8 is rotated thetubular member 10 will be sutticient distance out of the liquid to pick up the gases and convey them from one end to the other will be clear.

ln operation the machine is started and as the gases enter through the inlet they are picked up by the tubular member and directed by the spiral partition through the liquid and discharged at the outlet end in a condensed and separated condition ell'eeted during the travel through the said member.

The plate 14- plays an important part: in the arrangement of my eonvcyer in that it aids materially and actually prevents the wash and surge of the Water or liquid in the inlet chamber, keeping the liquid in a quiet state and a level surface and at all times allows the inlet end of the frustum to r *ceive its full capacity of gas or vapor. The per forated plate adjacent the discharge portion receives the fluid from the discharge end and breaks up all bubbles and aids in liberating the gas. It will be apparent. that this plate extends a sutlicient distance above the normal level of the liquid within the casing l in order that bubbles and the like discharged above the level may be broken up.

It will now be apparent that I have devi ed a novel and useful construction which embodies the features of advantage enumer- :ltt d as described in the statement of llhclltion and the above description, and while 1 have in the present instance shown and described a preferred en'ibodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be UlltltEl'StUUtl that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
